Connector for coaxial cable

A microwave connector assembly comprising:

• a terminating flexible microwave coaxial cable including an inner conductor, an intermediate dielectric, an outer flexible braided conductor, and an outer insulator, constructed and arranged to conduct effectively electrical signals of at least 30 GHz;
• a bored interface body having a first end with a first bore of relatively large inner diameter and a second end with a second bore of relatively smaller inner diameter adapted to receive said intermediate dielectric therein, and a radially inwardly extending wall formed between said first bore and said second bore;
• a coupling member proximate said interface body;
• and
• an annular locking member having an inside surface sized to receive said outer insulator of said coaxial cable therein and bonded by means of a bonding agent to said outer insulator thereof, an outer diameter sized to fit tightly within said first bore of said interface body, a first end and a second end, said second end being insertable within said first end of said interface body and adapted to urge said outer flexible braided conductor against said wall to essentially lock said flexible coaxial cable to said connector;
• wherein said bonding agent is a high flexural strength rigid epoxy resin that eliminates movement between said coaxial cable and said annular locking element and provide antirotational captiviation of up to ±90 degrees during repeated mating and demating cycles.

A microwave connector assembly comprising:

• a terminating flexible microwave coaxial cable including an inner conductor, an intermediate dielectric, an outer flexible braided conductor, and an outer insulator said microwave flexible coaxial cable being constructed and arranged to conduct signals in the microwave range that exceed 30 GHz;
• a bored interface body having a first end with a first bore of relatively large inner diameter, a second end with a second bore of relatively smaller inner diameter than said first bore, and a third bore located therebetween of relatively smaller inner diameter than said second bore;
• a coupling member proximate said interface body;
• an annular locking member having an inside surface sized to receive said coaxial cable therein and bonded by means of an epoxy resin bonding agent to said outer insulator thereof, an outer diameter sized to fit tightly within said first bore of said interface body, a first end and a second end, said second end having a plurality of ribs disposed proximate thereto, so that upon insertion of said second end of said locking member within said first bore of said interface body, said ribs frictionally engage the inner wall of said first bore to lock said locking member to said interface body;
• wherein said epoxy resin is a high flexural strength rigid epoxy resin that eliminates movement between said coaxial cable and said annular locking element and provides antirotational captivation of up to ±90 degrees during repeated mating and demating cycles.

A microwave connector assembly for connection to an electrical device, comprising:

• a terminating flexible microwave coaxial cable including an inner conductor, an intermediate dielectric, an outer flexible braided conductor, and an outer insulator adapted to conduct microwave signals of at least 30 GHz;
• a coupling nut adapted to connect said microwave flexible cable to the device;
• and
• an annular locking member having an inside surface sized to receive said outer insulator of said coaxial cable therein and bonded by means of a bonding agent to said outer insulator thereof, said annular locking member being coupled to said coupling nut;
• wherein said bonding agent is a high flexural strength rigid epoxy resin that eliminates movement between said coaxial cable and said annular locking element and provides antirotational captivation during mating and demating cycles.
